2. In a fluid operated damper regulator, a longitudi'iallv expansible ehamber having a elosed uppel head with deep bearing boss therein, an adjustabl'v fulerumed damper operating member pivoled above the expanwilde chamber. and a strut interposed between the damper operating member and 'the eed of the expansiblev Chamber and 2eme, y mounted in the deeply reeessed boss -f1llii`fil l fi, damper i'iegulator eomprisin I' a eolble chamber having a deeply lleeessed s in the upper closed head thereof. a lve operating member mounted to oseillate ilove the head oll the ehamber. and a strut 5 o ely .seated in the reeessed boss with the upper end portion bearing against the damper regulating member.

i, In a fluid pressure operated damper iegulator, a longitudinally expansible ehanlber, a headtherefor having a deeply reboss extending well into the chamber,

strut loosely seated in the boss with the lower end thereof in rocking Contact with the end face of the boss recess, a pivot block oscillatory above the chamber having a reeess in` its lower face against which the upper end portion of the stud bears, and a damper operating member adjustably 4mounted on the pvot block.

extending loosely into the reeess boss with the upper end portion bearing against a reeess in the lower tace of the pivot block, and a damper operating member adjustably mounted in the pivot block.

G. A damper regulator comprising a easing having`a base with an inlet nipple and opening therein, a longitudinally expansible ehamber having a deeply corrugated side wall, the lower fold of 'which has a central opening and flange around the opening seeured in the easing base inlet opening for supporting the chamber in the Casing, a head on the ehamber having a deeply reeessed boss extending above and below the head and moving freely in a guide opening through the head of the easing, an oscillatory bearing block fulerumed on the easing, a damper operating member adjustably mounted in the block, and a strut loosely seated in the deep reeess of the chamber head boss with the upper end contacting with the lower face of the pivot block.
